Red E528, a Dutch bird from the Maasvlakte colony (51.58 N, 04.02 E). Although pale-headed, this is another rather typical, if much more worn, graellsii. All scapulars have been replaced and by June these are very worn brown feathers; a single feather is of third generation. Several wing coverts and two tertials have recently been replaced. Some of the new median coverts are of a plain type whereas others are more buff with dark markings. They contrast strongly with the abraded juvenile feathers. In July (plate 3), the first complete moult is well underway: P7-10 are juvenile and P5 is growing. Most greater coverts are missing. It now is replacing scapulars; the feathers on the head also have been renewed.
